Jax-1. 12, 1932. F. HUsA SANITARY MILK BOTTLE Filed Aug. 25, 1928 fdflM-gmvENToR j?, ATTORNEY Patented Jan. 12, 1932 PATENT oFFlcE FRANK RUSA, F CAMDEN, NEW JERSEY SANITARY MILK BOTTLE Application led August 25, 1928. Serial No. 301,958.

The present invention relates to an improved milk bottle, and one which is sanitary in every respect. v It is a well established fact that a great many contagious diseases are transmitted by unclean milk bottles, even though they are cleansed by washing machines using hot water, due to the fact that a great manyof the germs collect in the corner at the bottom of the bottles and around the mouth end of the bottle, and due to these facts it is-the purpose of the present invention to provide a bottle made from paper pressed into shape,

particularly to resemble all milk bottles now l5 in use, such paper to be treated with parafine or similar material or substance, either prior to the formation of the bottle or subsequently, in order to render the bottle sanitary in every respect.

Another purpose is to provide a bottle of this kind having a seam or joint across the bottom and at one location on the side of the bottle, the seam or joint including a clamping strip having teeth to insure agalnst leakage, the joint also extending into the rim around the mouth end of the bottle.

Another purpose is to provide a milk bottle pressed into shape from paper of the desired thickness, including a right angle 3 marginal flange at the mouth end of the bottle having a clamping strip, said strip being so disposed as to provide a shoulder between which and a ledge of the flange a sanitary milk bottle cap may be inserted, acting to retain the cap in position.

It is to be understood that the particulars herein given are in no way limitive, and that while still keeping within the scope of the invention, any deslred modiication of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view in side elevation of the improved milk bottle constructed in accordance with the invention.

Figure 2 is a vertical sectional view through the same, showing the construction of the seam or joint in the bottom of the bottle and the construction of the margin of the mouth end of the bottle, with the vertical seam shown in Figure 1 cut awa F lgure 3 is a cross sectidnal v1ew through a bottle, showing the joint or seam extending from dlametrical opposite portions of the sides of the bottle and through the bottle.

Figure 4 is an enlarged detailed view of the side of the bottle, showing the joint partly formed.

Figure 5 is a detailed view of the section of the clampingstrip.

Figure 6 is an enlar ed detailed sectional view of a portion of t e mouth end of the bottle.

Figure 7 is an enlarged detailed sectional view of a portion of the mouth end of the btc ttle8 showingv a modified form of metal s rip Referring to the drawings, 1 identifies a milk bottle which may be any size or shape and preferably constructed of any suitable paper -whlch may be pressed, molded or otherwlse formed so as to take the shape of the now generally used glass milk bottle. The pressing or molding of the bottle may be accomplished by any well known method.

However, paper or similar fibre when shaped and the opposite edge flanges 2 are brought together and interlocked, as shown -in the enlarged detailed view of Figure 4, a

sanitary milk bottle or container may be formed.

Prior to pressing the flanges tightly together the meta-l strip 3 is bent longitudinally upon itself straddling the ,overlying flange o the seam or joint, and since the strip has 'teeth 5 on its longitudinal edges the teeth clinch into the anges, and by pressing said parts together a secure joint or seam is provided, one such as will avoid any leakage of the liquid to be contained in the bottle.

The upper margin of the bottle is pressed to form a horizontal ledge 6 provided with an upstanding marginal flange 7, and straddling therange and engaging under the ledge, conforming to the ledge and the Aflange is a metal strip 8 which and the strip 3 may wi be made of relatively thin pliable metal, to v enable it to be pressed into shape.

A ange 9 of the strip 8 is ositioned on the interlor of the flange 7, an the toothed edge 10 of the llange is out-turned and adapted to pierce or engage vinto the Bange' to secure the stri in position.

The toothed e ge 10 of the ange 9 is so disposed relative to the ledge 6 as to provide an annular groove or crevice 11 in which the marginal edge of a milk bottle cap may engage to retain the cap in osition and in such a manner as to prevent eakage.

In Figure 7 the mouth end of the bottle is slightly modified, to the extent of having the metal strip 8a straddling the mouth end of the bottle, and there being no ledge shown to hold the bottle cap, but the wall of the bottle is slightly inclined to prevent the bottle cap from being punched down in the bottle. A metal strip straddles the wall of the bottle at the mouth end and its teeth 10b are laterally bent in the material of the bottle.

When the bottle, as shown in Figure 3, is provided with a seam or joint formed along diametrically opposite portions and through the bottom of the body of the bottle, the bottle ma be made in two pieces.

he invention having been set forth, what is claimed is.

1. As an article of manufacture, a sanitary i milk bottle, constructed from pressed fibre, said bottle having a mouth and comprising a ledge extending around the interior of the mouth end and having an adjoining flange, and a metal strip straddlin the Bange annularly and under the ledge, t e inner portionof the metal strip provided with teeth to embed in the flange, the portion of the strip adjacent said teeth constituting an annular shoulder, between which and the ledge, the

marginal edge of a milk bottle cap may engage.

2. As an article of manufacture, a sanitary milk bottle constructed of pressed fibre, said bottle having a mouth and comprising a ledge and extending around the interior of the mouth end and having an adjoining flange,

and a metal strip straddling the ilange an-l nularly and under the ledge, the inner edge portion of the metalk strip constituting an annular shoulder, between which and the ledge, the marginal edge of the milk bottle cap may engage.

In testimony whereof he aixes his signature.
